Abstract
A pressure adjustment apparatus includes a compartment and a valve arrangement for regulating compartment pressure. The valve arrangement includes an inlet for connection to a pressurized fluid source with an inlet valve, an outlet with an outlet valve, a compartment port connecting the compartment, and a compartment valve controlling fluid flow into and/or out of the compartment. The compartment valve is configured for simultaneous actuation to an open position with the inlet and/or outlet valve, enabling fluid flow into or out of the compartment when either the inlet or outlet valve is open. The apparatus may include actuators for the valves, resilient biasing arrangements, a pressure relief valve, and can be configured as a unit with multiple valve arrangements connected to shared conduits, with features for sealing and compactness.
